Phar::extractTo — Extract the contents of a phar archive to a directory

### Beschreibung

public Phar::extractTo(string `$directory`, array|string|null `$files` = `null`, bool `$overwrite` = `false`): bool

Extract all files within a phar archive to disk. Extracted files and directories preserve permissions as stored in the archive. The optional parameters allow optional control over which files are extracted, and whether existing files on disk can be overwritten. The second parameter `files` can be either the name of a file or directory to extract, or an array of names of files and directories to extract. By default, this method will not overwrite existing files, the third parameter can be set to true to enable overwriting of files. This method is similar to ZipArchive::extractTo().

### Parameter-Liste

`directory`

  Path to extract the given `files` to

`files`

  The name of a file or directory to extract, or an array of files/directories to extract, `null` to skip this param

`overwrite`

  Set to `true` to enable overwriting existing files

### Rückgabewerte

returns `true` on success, but it is better to check for thrown exception, and assume success if none is thrown.

### Fehler/Exceptions

Throws PharException if errors occur while flushing changes to disk.

### Beispiele

Beispiel #1 A Phar::extractTo() example

`<?php
try {
$phar = new Phar('myphar.phar');
$phar->extractTo('/full/path'); // extract all files
$phar->extractTo('/another/path', 'file.txt'); // extract only file.txt
$phar->extractTo('/this/path',
array('file1.txt', 'file2.txt')); // extract 2 files only
$phar->extractTo('/third/path', null, true); // extract all files, and overwrite
} catch (Exception $e) {
// handle errors
}
?>`

### Anmerkungen

> Hinweis:

> Windows NTFS-Dateisysteme unterstützen einige Zeichen in Dateinamen nicht, nämlich `<|>*?":`. Dateinamen mit einem Punkt am Ende werden ebenfalls nicht unterstützt. Im Gegensatz zu einigen Extraktionswerkzeugen ersetzt diese Methode diese Zeichen nicht durch einen Unterstrich, sondern extrahiert solche Dateien nicht.
